This is still reproducible in today's trunk Fennec build on the Galaxy Nexus.
I'm seeing it in fact with various overflow: scroll blocks.

I'm pretty certain this was fixed by BenWa's patch to invalidate on tile format change and I can't reproduce it. I can't find the bug number now... Marking this as fixed, please re-open if you can reproduce.
